About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-75S
The AirTAC SAIJ32X230-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This creates a highly versatile 155-230 mm usable stroke window, letting you dial in the exact retract position without swapping out the barrel or adding external stops. In the compact 32 mm bore class, it delivers a push force of 563 N at 0.7 MPa, making it well-suited for lighter-duty positioning and end-stop tuning tasks.
This specific SKU is configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. The -S magnet option enables position feedback via AirTAC CMSE reed and DMSE electronic solid-state sensors, which drop directly into the dual-side sensor grooves on the extruded aluminum barrel. It uses a PT tapered port thread (G1/8) and relies on the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) for full ISO 15552 interchangeability.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-75S Is Used
End-Position Tuning
Dial in the exact retract stop from 155 to 230 mm during machine commissioning without machining external stop blocks.
Product Changeover
Quickly adjust the stroke window on packaging lines when handling slightly different carton or part sizes.
Light Diverter Arms
Provides 563 N of push force at 0.7 MPa for accurately positioning lightweight items on a conveyor belt.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-75S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires precise retract-position tuning during commissioning or frequent product changeovers, benefiting from the 155-230 mm travel window. If your setup needs greater thrust, stepping up to the 40 mm bore neighbor provides 879 N of push force at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 230 mm nominal stroke, 75 mm adjustment range, PT G1/8 port, and the required SAIJ mounting accessory. Because the stroke is 230 mm, ensure proper guidance to prevent excessive side-loading on the 12 mm rod and M10x1.25 rod thread.

- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-75S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm, providing a usable travel window of 155 to 230 mm. It acts as a physical stop to fine-tune the end position, but it is not a lock and will not hold the load without continuous air pressure.
At 0.7 MPa, the SAIJ32X230-75-S generates a push force of 563 N and a pull force of 345 N. At the maximum operating pressure of 1.0 MPa, it can deliver up to 82 kgf of push force.
